Sound Devices 633 - Manual (Page 20)

Inputs
The 633 has three, full-featured audio inputs on XLR-3F connectors and three additional line-level
inputs on TA3 connectors. Inputs can be used as either balanced or unbalanced connections. To un-
balance, tie pin-3 to pin-1 of the XLR-3M connector of the cable. There is no change in gain between
unbalanced and balanced connections into the 633.
Inputs are configured from their respective input Settings Screen. The default method for accessing
the Input Settings Screen for inputs 1-6 is to slide the Input Select Switch toward the desired input
number. This functionality can be altered when Setup Menu option INPUTS > PFL Toggle Mode is
set to 3ch ( See “PFL Toggle Mode”, page 25 ).
Input Types
Change the input type from the Input Settings Screen ( See “Input Settings Screen”, page 11 ).
The following table describes the available input types.

Input Routing
Each input of the 633 has a corresponding “ISO” Track that it is permanently routed to. Addition-
ally, each Input can be independently routed to the Left (L), Right (R), Aux 1 (X1), and/or Aux
2 (X2) buses from the Input Settings Screen ( See “Input Settings Screen”, page 11 ). Inputs are
routed to the Aux 1 (X1) and Aux 2 (X2) buses from the X1, X2 Routing Screen (Setup Menu option
OUTPUTS > X1, X2 Routing) and to the Aux 3 (X3) and Aux 4 (X4) buses from the X3, X4 Routing
Screen (Setup Menu option OUTPUTS > X3, X4 Routing).
Input signals are always routed to L and R tracks post-fader. The Pan Control variably adjusts the
level of Input 1, 2, or 3 signal to the L and R tracks. Input signals can be routed to ISO tracks and X1,
X2, X3, and X4 tracks either pre- or post-fader.
• Pre- or post-fader routing to ISO tracks is set per channel from Setup Menu section
INPUTS > Input to ISO Routing .
• Pre- or post-fader routing to X1 and X2 tracks is set from the Input Settings Screen. From the Input
Settings Screen, slide the Mic / Tone Switch to cycle between unrouted (black background), routed
post-fader (red background), and routed pre-fader (red background with PRE label).
